Mapping climate change vulnerability of older Australians to extreme heat. Exposure to extreme heat is associated with negative health outcomes and has been recognized as a global health challenge in the context of climate change, especially among older people. While the direct heat-related mortality for older people reached a record high of 345,000 deaths worldwide in 2019, which was 80.6% higher than the 2000–05 average, there has been no detailed study in Australia. This project is to have a ....Mapping climate change vulnerability of older Australians to extreme heat. Exposure to extreme heat is associated with negative health outcomes and has been recognized as a global health challenge in the context of climate change, especially among older people. While the direct heat-related mortality for older people reached a record high of 345,000 deaths worldwide in 2019, which was 80.6% higher than the 2000–05 average, there has been no detailed study in Australia. This project is to have a national picture of the impact of extreme heat on the health outcomes of older people and associated healthcare costs at Statistical Area level 3 (SA3), to inform the design and implementation of tailored interventions to minimize the health risk and costs from extreme heat to protect the health of this vulnerable group.

Evolution in tooth and claw: exploring the relationship between the radiation of marsupial herbivores and late Cenozoic climate change. Establishing how animals responded to past environmental changes is essential for understanding the ecology of modern species and managing them in light of contemporary climatic trends. By applying several novel analytical methods this project will unravel the links between the radiation of Australian marsupials and key stages in climatic evolution.
Occupational injury prevention in high temperature environments. This project aims to explore the contribution of heat as a risk factor in work-related illness and injury. Approximately 600 000 Australians experience a work-related illness or injury each year. Hot weather may directly or indirectly lead to accidents, but heat as a risk factor has not been systematically explored, and is particularly relevant in a warming climate. This project aims to improve safety and productivity in Australian ....Occupational injury prevention in high temperature environments. This project aims to explore the contribution of heat as a risk factor in work-related illness and injury. Approximately 600 000 Australians experience a work-related illness or injury each year. Hot weather may directly or indirectly lead to accidents, but heat as a risk factor has not been systematically explored, and is particularly relevant in a warming climate. This project aims to improve safety and productivity in Australian industry by generating new evidence and predictive models to inform injury prevention policy and guidance, and facilitating the development of practical, targeted resources. This project expects to add to the body of knowledge regarding workers’ health and safety and to be of benefit to industry and subpopulations at risk.Read moreRead less
Molecular switches and genetic consequences of grain retention in cereals. Grain retention at maturity was key for crop domestication and laid the basis for farming. Wheat and barley have evolved a novel mechanism for ensuring grain retention and, although the genes are known, the mechanisms for action are not. Grain dispersal in the wild relatives involves highly targeted changes in the walls of a small number of cells. This project will explore how the two identified genes control this proces ....Molecular switches and genetic consequences of grain retention in cereals. Grain retention at maturity was key for crop domestication and laid the basis for farming. Wheat and barley have evolved a novel mechanism for ensuring grain retention and, although the genes are known, the mechanisms for action are not. Grain dispersal in the wild relatives involves highly targeted changes in the walls of a small number of cells. This project will explore how the two identified genes control this process and clarify their mode of action. The genes ensuring grain retention have been so critical for domestication that the region surrounding them has become genetically fixed. The project will assess the implication of fixation on genetic diversity and develop options to bring novel variation into breeding programs.Read moreRead less
Fire and rain: Drivers of deep-time ecosystem assembly in Australia. This project aims to investigate the influence of bushfires and shifting rainfall patterns on the development of Australia’s dominant ecosystems. By combining a range of novel geochemical, isotopic and palaeontological techniques, this research seeks to reveal the causes and consequences of Australia’s transformation from a forested to mainly open landscape of grassland, shrubland and savannah. The expected outcome is detailed ....Fire and rain: Drivers of deep-time ecosystem assembly in Australia. This project aims to investigate the influence of bushfires and shifting rainfall patterns on the development of Australia’s dominant ecosystems. By combining a range of novel geochemical, isotopic and palaeontological techniques, this research seeks to reveal the causes and consequences of Australia’s transformation from a forested to mainly open landscape of grassland, shrubland and savannah. The expected outcome is detailed knowledge of how changes in fire and rain shaped the ecology and evolution of plants and animals. This knowledge is key to understanding how Australian ecosystems function and to protecting their cultural, economic and environmental values, especially as climate and fire regimes continue to change into the future.Read moreRead less
Faunal responses to environmental change and isolation on an Australian land-bridge island. Establishing how faunas responded to past isolation and environmental changes offers great potential for predicting long-term impacts of habitat fragmentation. By combining novel methods we will track extinction rates, diet and body-size shifts on Kangaroo Island, the only known land-bridge island with a fossil record spanning the past 100,000 years.
Plastic brains: Neural adaptations to changing environments in reptiles. The project aims to quantify brain anatomy on an unprecedented scale in comparative neurobiology. Focusing on Australia’s diverse and extensive collection of reptiles, including goannas, dragons and venomous snakes, the project expects to generate new knowledge on the evolution of brains as these animals adapted to new habitats and climates. Data will be collected by cutting-edge micro-CT technology and advanced phylogeneti ....Plastic brains: Neural adaptations to changing environments in reptiles. The project aims to quantify brain anatomy on an unprecedented scale in comparative neurobiology. Focusing on Australia’s diverse and extensive collection of reptiles, including goannas, dragons and venomous snakes, the project expects to generate new knowledge on the evolution of brains as these animals adapted to new habitats and climates. Data will be collected by cutting-edge micro-CT technology and advanced phylogenetic techniques, which will be complemented by detailed neuroanatomy. Expected outcomes include enhanced understanding of the effects of temperature on brains, and a large database of 3D digital anatomical models. A major benefit includes a greater ability to mitigate the effects of environmental change.Read moreRead less
